What this tool does

The result rebuilds complete Hangul syllables where valid jamo sequences are found and reports parts that could not be composed safely.

Maps compatibility jamo to Hangul composition indexes and applies the Unicode formula: 0xAC00 + initial×588 + medial×28 + final.

Use the validation report to find missing vowels or jamo in the wrong order.

Example

Input “ㄱ ㅏ ㄴ” and get “간”.

Use cases

  • Recovering decomposed Korean text.
  • Testing Korean input method logic.
  • Cleaning OCR or encoding output.

Tips for better output

  • Use initial → medial → optional final order.
  • Separate syllables with spaces for best accuracy.
  • Check invalid sequence output before copying.

Processing details

The combiner supports common compatibility jamo such as ㄱ, ㅏ, and ㄴ. It can read spaced jamo groups or compact sequences when possible.

Ambiguous unspaced jamo may require manual correction. Some archaic Korean jamo are not included in the modern syllable formula.

FAQ

How do I combine Hangul jamo into Korean syllables?

Paste jamo such as ㄱ ㅏ ㄴ and run the combiner. Valid initial, vowel, and final sequences are converted to complete Hangul.

Why are my Korean letters not combining correctly?

The sequence may be missing a vowel, have the wrong order, or contain unsupported jamo.

Can I rebuild Korean text from separated jamo?

Yes, if the jamo are modern Hangul components and the sequence is clear enough to compose.

How does Hangul composition work in Unicode?

Unicode calculates each syllable from initial, medial, and final indexes using a fixed formula.

How do I fix invalid Korean jamo sequences?

Use the invalid sequence report to find the position, then add the missing vowel or separate ambiguous syllables.
